Now 74-years old, López Rivera has served 35 years of a 55-year sentence for seditious conspiracy and weapons-related charges. “I am an enemy of the United States government,” he told federal judge Thomas McMillen in 1983. There is no evidence that he’s changed his mind.

During the 1970s and 80s, López Rivera’s FALN placed more than 130 bombs in American cities. Their goal was to destabilize what they called the “Yanki capitalist monopoly” and achieve Puerto Rican independence. Their method was terrorism.

When López Rivera was arrested in 1981, the FBI found six pounds of dynamite and four blasting caps in his Chicago apartment along with numerous fake IDs. He was convicted in federal court of seditious conspiracy, violation of the Hobbs Act, illegal weapons possession, and interstate transportation of stolen motor vehicles.

In 1988, his original sentence was extended 15 years after authorities disrupted an escape plot that included a plan to murder prison guards.
